With the rapid development of domestic automobile production and production, the development of automobiles has become more and more important, and trial production is an important part of automobile development. As an important means, hand-board proofing technology is increasingly applied to the development of automobiles. Trial prototypes can be used as visualizations, design evaluations, interference checks, and even some functional tests of CAD digital models.
For auto parts, the model family generally uses CNC machining. Its advantages are that it can accurately reflect the information expressed on the drawings. Moreover, the surface quality of the CNC hands is high, especially after the completion of surface painting and screen printing. The products produced after the molds are opened are to be radiant.
The need to make a car hand:
1) Test appearance design: The hand board is not only visible but also touchable. He can intuitively reflect the designer's creativity in the form of physical objects, avoiding the “painting out to look good and do not look good” Disadvantages. Therefore, the production of Shouban is indispensable in the development of new products and the scrutiny of product appearance.
2) Inspection structure design: Because the hand board is assembleable, it can intuitively reflect whether the structure is reasonable or not, and how easy it is to install. It is easy to find problems and solve problems early.
3) Avoid the risk of directly opening the mold: As the cost of mold manufacturing is generally high, the price of the relatively large mold is in the range of 100,000 to several million. If the structure is found to be unreasonable or other problems in the process of opening the mold, its loss will occur. Can imagine. It is possible to avoid this loss and reduce the risk of mold opening by doing the handboard until confirmation.
The car hand board can make the user intuitively understand the appearance and performance of products that have not been put into mass production and can make timely evaluation, so that the factory can timely improve products according to the needs of users and market research, create favorable conditions for the sale of products and avoid Blind production may cause damage.
